Invalid E-Mail error on valid email

[moritztim]

I ran just this function locally and it worked, but when I try to sign up on the production website, I get an Email invalid. error for an email that is registered using cloudflare e-mail forwarding.

	func IsEmailValid(email string) bool {
	length := len(email)
	if length < 3 && length > 254 {
	return false
	}
	if !emailRegex.MatchString(email) {
	return false
	}
	parts := strings.Split(email, "@")
	mx, err := net.LookupMX(parts[1])
	if err != nil || len(mx) == 0 {
	return false

	return true
